3D printing: Recent advancement and usage
                     3D PRINTING: RECENT 
ADVANCEMENT AND USAGE
INTRODUCTION
3D printing (the primary form of 
additive manufacturing) has truly 
changed the game for prototyping 
and production of parts.

HOW DO 3D 
PRINTERS 
WORK?
STEP 1
The first step in the creation of a 3D 
printed object is to design the 
object. This is done in a 3D art, CAD 
(Computer-Aided Design), or 
animation program. The computer 
model is then exported as an STL 
file.

PRINTERS 
WORK?
STEP 2
A second program, known as a 
slicing program, reads the STL file 
and converts it to G code. This code 
tells the printer to produce the 
object in a series of horizontal 
layers. The printer then prints these 
layers one at a time, starting with 
the bottom layer.

3D PRINTERS 
FOR 
CONSUMERS
Consumer-oriented FDM printers 
are dropping in price and are 
becoming more affordable. It's no 
longer necessary to spend 
thousands of dollars to buy a 3D 
printer for the home.

3DOODLER PEN 
VERSIONS ONE 
AND TWO
The 3Doodler was the first 3D pen 
created (as far as I know), but it 
now has multiple competitors. The 
video above shows some of the 
objects that it can create.

DRAWING WITH 
A 3D PEN
The pens enable people to draw 
with extruded plastic on a flat 
surface or in the air. Both one-
dimensional objects with a raised 
surface and true 3D objects can be 
created.

3D PRINTER: A 
POLL
Some 3D printers have a sleek and 
modern design. The mechanism is 
hidden, as in a microwave oven. In 
other printers, as in the one above, 
the parts are clearly visible and 
there is no attempt to make the 
printer attractive.

DISADVANTAGE
Plastic pollution is a serious 
environmental problem. The 
thought of people discarding 
unsatisfactory objects created by 
their 3D printers is scary. The 
problem may become worse as the 
printers become more popular.

THE FUTURE OF 
3D PRINTING
Some people predict that a 3D 
printing revolution will take place in 
the near future. The printers are 
rapidly gaining acceptance in 
manufacturing and have exciting 
applications in medicine.

REQUIREMENTS 
FOR SUCCESS
3D printers for consumers need to have at 
least some of the following features in order 
to be successful. They should be able to:
• create useful items more conveniently or 
more cheaply than the same item made 
by other methods
• create high-quality objects
• make improved versions of objects 
manufactured by other methods
• make objects that couldn't be created in 
any other way
